Frausto silicones

  1. 1. SiliconesSilicones
  2. 2. What are Silicones?What are Silicones? are synthetic polymers with a linear, repeatingsilicon-oxygen backbone Silicone polymers do not have carbon as part of thebackbone structure Have a high melting and boiling point Depending on the number of repeat units in thepolymer chain and the degree of cross-linking, sixclasses of commercially important products can beproduced Some disadvantages of Silicone are increased costsand lower mechanical property values whencompared to carbon based materials
  3. 3. Forms & CompositionsForms & Compositions Fluids, Emulsions, Compounds, Lubricants, Resins andrubbers Varies from liquid to gel, or rubber to hard plastic odorless and colorless, water resistant, chemical resistant,oxidation resistant, stable at high temperature, and haveweak forces of attraction, low surface tension, low freezingpoints and do not conduct electricity seem to be impervious to the effects of aging, weather,sunlight, moisture, heat, cold, and some chemical assaults
  4. 4. Silicone ProductsSilicone Products Caulking Breast implants Lubricants Adhesives Sealants Gaskets Silly putty Few thousand other forms
